Verified Answer :

A = a^2
144 = a^2
sqrt 144 = a
12 = a.....each side of the square is 12 cm

Answer:

The length of one of the side of the square is 12 cm.

Step-by-step explanation:

Area of the Square = 144 cm²

let s be the side of the square.

According to the question,

\(s\times s=144\)

\(s^2=144\)

\(s=\pm\sqt{144}\)

\(s=\pm12\)

negative value of s is rejected as side can never be negative.

Therefore, The length of one of the side of the square is 12 cm.
